Where the Water Stands

Depth to a Perched Water Table and Partial Resistance to Phytophthora Root Rot across a Piezometer-Gridded Lucerne Nursery

A paper from the School of Underlying Conditions sows twenty lucerne breeding lines and two checks in six contour bands down one hillslope, with a piezometer in each of 132 plots, and scores Phytophthora root rot over two winters against the days water stood within 30 cm of the surface. The upper slope barely separated the entries, the middle slope ranked them almost as the waterlogged toeslope did, and five lines kept their roots nearly clean the whole way down while three upslope favourites failed.
